I have a Dell laptop and a HP Laptop using both for Doxy Video calls and Zoom callsProblem---upon starting the video call--everything is working---can see myself and the person I have invited to the call.My camera become disabled and therefore my picture goes awayI can enable the camera and its goes on for a minute or two and then drops againI'm wondering, based on other discussions I have read with no solution as of today if we all have the same security system and this is blocking in some way?I have Norton---360 seemed to work fine and then issues started occurring with my laptops upon using

Re CAMERA connect for Zoom meetings

How do I get the ZOOM app onto the Privacy access list?

I'm not having any luck in unblocking the camera. I can see and hear at Zoom meetings, but not seen.

Does Zoom need Windows permission? How do you fix that? I'm not very good at tech mazes; maybe someone

can walk me through that needed connection? Why is Zoom omitted from the apps with access list?

Error number received at clicking the video sign to join: #OxA00F4244 [no connection)

Checked re App Access which are all marked ON, but no Zoom app listed.

Suggestions, recommendations?
